micknater Posted July 17, 2015 Share Posted July 17, 2015 Hello all , first sorry about my bad english. I have a question about 3DS Max Vray 3.0 light settings for many lights . My scene is an interior office corridor with 45 Vray light planes. Problem is that even if I increase the light samples and material samples, the image noise is. Only when I put in Probabilistic light 48, the image is noise-free. Or uncheck Probabilistic is also the Images noise-free. But the render time is now inefficient . Anyone a idea which Setting can help me , to deal with many light ? Link to comment Share on other sites More sharing options...
Francisco Penaloza Posted July 17, 2015 Share Posted July 17, 2015 Hi Mic, it is hard to give you a straight answer to your question, because there is too many variables. Also an image of what you are working on will really help. also displaying your settings. As a rule of thumb, if we can call it that way, When more lights you use in V-Ray it will take longer to render, that is part of this process no way around. Now how much it is too much, that depends, how many machines you have, what size of rendering. and overall complexity of your scene. 30 minutes can be fine, but also 3 hours can be a regular for a large size image. even 9 hours for those brute force lovers. more info is need it to to give you a better answer. Cheers. Link to comment Share on other sites More sharing options...
Rich O Posted July 18, 2015 Share Posted July 18, 2015 have you tried cranking probabalistic to 64, or even 128 samples? I'd still think that would be quicker than not using probabalistic at all, and should still look pretty good. Link to comment Share on other sites More sharing options...
micknater Posted July 18, 2015 Author Share Posted July 18, 2015 Am I wrong , brings a higher value in probabalistic not a higher render time ? Link to comment Share on other sites More sharing options...
michelschweinsberg Posted July 18, 2015 Share Posted July 18, 2015 It could be many things outside of just the lights. It could be your vray render settings. Renderspaz is a great resource for vray and this sounds about what you're looking for. Link to comment Share on other sites More sharing options...
micknater Posted July 18, 2015 Author Share Posted July 18, 2015 I had little time I had to get this scene finished. But I got good reduces the rendering time. I thought it would be up to a value, but there were some of the values that needed to be adjusted. I thank you all very much that you have thought about my Problem.
